Cathodoluminescence microscopy of impurity phases in ZrO2/Ni nano–composites

Cathodoluminescence (CL) microscopy of Ni/cubic-ZrO2 nano–composites has been used to demonstrate the presence of both secondary phases and compositional fluctuations within the microstructure. X-ray microanalysis showed that in this material red CL emissions were generated from aluminium rich phases, blue emissions originated from silicon rich phases, and green CL emissions were associated with a monoclinic zirconia phase. In rapidly characterizing the distribution and density of these impurities, the CL technique has proved to be a powerful and versatile tool in the determination of the purity of sintered pellets.
